Aballoon is rising vertically at the rate of 12 feet per second; at the same time, it is being blown horizontally by a wind of 18 feet per second. find the angle its path makes with the horizontal.

34 degrees

Step-by-step explanation: tanΘ = opp/adj the opposite angle is 18 and the adjacent angle is 12, this is because the triangle is upside down thus, the 90 degrees is formed with the horizontal, and theta is the part of that 90 degrees made with the horizontal. Therefore, solve for the angle inside the triangle then subtract that from 90 and you have theta.

1,918

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
